DRAINAGE APPARATUS.

SPECIFICATION forming part of Letters Patent No. 665,826, dated January8, 1901.

Application leddune 19, 1900. Serial No. 20,898. (No model.)

To @ZL Lch/m, t may concern.-

Be it known that I, SAMUEL C. CARROLL, a citizen ofthe UnitedStates,residing at Dallas, county of Dallas, State of Texas,.haveinvented certain new and useful Improvements in Drainage Apparatus, of whichthe following is a specification.

The object of my invention is to provide means for carrying off thedrainage and sewage from cities situated upon rivers or the ocean thetide-waters of which are elevated above the same, which necessitates theprovision of levees or dikes, and to discharge the sewage into saidriver or ocean. To accomplish this purpose, a basin is provided in thecity into which the sewage and surface water, Snc., drains, and meansare employed for siphoning the water collecting thereinto over thelevees into the river or ocean. The present invention relates moreparticularly to the arrangement of the siphoning apparatus and includesa main siphon-pipe, adevice located at the discharge end thereof forstarting the flow through said pipe and accelerating the same, and anauxiliary siphon to prevent the basin from being drained, whichwouldinterrupt the siphoning action.

The invention is illustrated in the accompanying drawings, in which-Figure 1 shows the general arrangement of the apparatus, and Fig. 2 is adetail view. Fig. 3 is a modiiication.

A basin 1, which receives the drainage from the city, is shownconventionally7 separated from the river 2 by a levee or embankment 3,and, as will be noted, the surface of the water representing thetide-level is higher than the water in the basin.

At a suitable point in the river-bed a masonry column e, about six feethigh, is built, which supports a pipe 5, placed parallel with the ow ofthe current, the pipe having an enlarged flaring mouth 6. Back ofthemouth the long leg ot' the siphon-pipe `'7 communicates therewith andextends therefrom at an acute angle up and over the levee, its oppositeend S depending into the basin 1. A neat-operated valve 9 controls theinlet into this end, and, as will oe seen,this valve opens into the pipeand is held raised from its seat by the float 11 as long as the water inthe basin maintains a predetermined level. If

the water drops below this level, the ball drops and the valve closesagainst back pressure of the water. On starting the apparatus, it beingnecessary that the pipe be full of water from end to end, I haveprovided a tank 10, having a connection 11 communieating with said pipe'7, so that by opening the valve 12 the portion of the pipe 7 above thewater-level in the basin 1 and river 2 may be filled or primed withwater. As soon as the valve 9 is opened the force ofthe water rushingthrough the contracted part ofthe pipe will start the siphon, the waterruiming from the basin intoV the river. K To prevent the water in thebasin dropping below the level where the siphon would be interrupted, anauxiliary siphon 12' is provided, one end of which, 13, is placed justbelow the low-tide level in the river,while the Otherend depends intothe basin and -is provided with a floatcontrolled valve 14, whichnormally holds this end closed. The end 13 is provided with a suitablestrainer. A branch pipe 15 from the pipe 11 communicates with theauxiliary siphon, the communication being normally shut off by valve 16.If the water in the basin falls to the mean level necessary for the mainsiphon to operate,the auxiliary siphon will immediately operate,as theballvalve 14 will automatically open, and thus water from the river willsiphon into the basin until the ball-valve closes the auxiliary pipeagain. In case of necessity the auxiliary siphon may be primed throughthe pipe 15, controlled by the valve 16.

A suitable oat may be placed in the tank 10, provided with an indicatorto show the depth of water therein.

In Fig. 3 I have shown a modification in which the funnel-shapedreceiver is arranged at right angles to the line of the shore, so as toutilize the motion of the waves when it is desired to use the apparatusalong the line of the ocean or sea or anywhere that the motion of thewaves can be utilized instead of the current, as in the case of a river.

I claim as my invention-v 1. An apparatus-for siphouing water from..

the basin of a city into a body of water, the tide-waters of which areon a higher level than the same, over an interposed levee, comprising asiphon-pipe having one end depending IOO in said basin and the otherextending into the body of Water, and a pipe arranged parallel with thecurrent or motion of the body of water communicating with the end of thesiphon-pipe, substantially as described.

2. An apparatus for siphoning water from the basin of a city into a bodyof Water, the tide-waters of which are on a higher level than the same,over an interposed levee, comprising a siphon-pipe having one enddepending in said basin and the other extending into the body of Water,and a pipe arranged parallel with the current or motion of the Watercoinmunicating with the end of the Siphon-pipe, said pipe having anenlarged flaring mouth, substantially as described.

3. An apparatus for siphoning Water from the basin of a city into a bodyof Water, the tide-Waters of which are on a higher level than the same,over an interposed levee, comprising asiphon-pipe having one enddepending in said basin, and the other extending into the body of water,and a pipe arranged parallel with the current or motion of the Watercommunicating with the end of the Siphonpipe, and a loat-valvecontrolling the end of the siphon depending into said basin,substantially as described.

4. An apparatus for siphoning Water from the basin of a city into a bodyof Water, the tide-waters of which are on a higher level than the same,over an interposed levee, comprising` a Siphon-pipe having one enddepending in said basin and the other extendinginto the body of water,and a pipe arranged parallel with the current or motion of the bodyofWater communicating with the end ofthe siphonpipe and an auxiliarysiphon to prevent the interruption of the action of the main Siphon,substantially as described.

5. An apparatus for siphoning Water from the basin of a city into a bodyof Water, the tide-Waters of which are on a higherlevel than the same,over an interposed levee comprising a main Siphon-pipe for conveying thewater from the basin into said body of Water, a back-pressure valve insaid basin, an auxiliary Siphon-pipe interposed between the body ofWater and the basin and means for automatically starting the tlow ofWater through the same from the body of water into the basin when thewater in the latter drops to a predetermined level, substantiallydescribed.

6. An apparatus for siphoning water from the basin of a city into a bodyof water such as a river or* ocean, the tide-Waters of which are on ahigher level than the same, over an interposed levee, comprising a mainsiphonpipe for conveying the Water from the basin into said body ofwater, a back-pressure valve in said basin, an auxiliary Siphon-pipeinterposed between the body of water and the basin, means forautomatically starting the ow of Water through the same from the body ofWater into the basin when the waterin the latter drops to apredetermined level and means for priming said main and auxiliarySiphon-pipes, substantially as described.

In testimon)` whereof I afx my signature in presence of two Witnesses.
